T0 aZZ whom it may concern:

Be it known that I, EZRA W. VAN DUZEN, J r.,a citizen of the United States and a resident of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Cooking Stoves and Ranges, of which the following is a specification.

The objects of this invention are to provide a cooking stove or range with all the conveniences of amodern cast-iron cooking-stove; to

wroughtiron stove or range and at the same time utilize to advantage all the heat; to so construct the oven as to equalize the heat therein; to provide the maximum amount of top cooking-surface and oven capacity, and to provide a judicious system of curves for a circulation of the heated air and gases which is nearly constant underall conditions and is evenly and uniformly distributed. These objects I accomplish by the construction of stove or range illustrated in the accompanying drawings, in which- Figure 1 is a perspective view with one of the side plates omitted to clearly show the interior of the stove or range; Fig. 2, a horizontal transverse sectional View on the line 2 2 of Fig. 1; Fig. 3, avertical sectional view on the line a? :v of Fig. 2; Fig. 4, a plan view of the main bot-tom plate of the stove or range; Fig. 5,2. longitudinal sectional view on the line 11g of Fig. 2; Fig. 6, a perspective view of the ash box or pan; Fig.7 ,a cross sectional view on the line z z of Fig. 1.

Referring to the drawings, the letter A indicates the main bottom plate of the stove or range which is preferably of cast-iron and is provided with lineal grooves a a to receive the vertical side and end plates, and with a side eXtension,A,to form the bottom of a vertical flue hereinafter described, and also with a front extension, A, to form a seat for an ash box or pan. The center of the cast-iron bottom plate, A, is open, and around the edges is formed an offset, a, which receives and sustains a wrought-iron center plate, A which is arranged fiush with the surface of the main bottom plate. This combined cast and wrought iron bottom plate enables me to dispense with the pan usually employed in ordinary stoves or ranges to prevent the bottom thereof from cracking.

The side plate, E, is provided with suitable openings for access to the tire and the oven, said openings being furnished with doors, as hereinafter described.

The back end plate of the stove or range is formed with two convex converging curves, 0 G, which prevent the sheet metal from warping, the upward-diverging curve 0 permitting the top plate, H, to be extended rearwardly, thereby increasing the heating-surface thereof, and permitting additional potholes to be provided at the rear.

The letter L indicates the curved oven, which is composed of two metal plates or casings, l l, which are curved or bent as shown, and placed relatively together to form double walls and create a continuous intervening air space or chamber. The oven, instead of being curved in a uniform manner, as shown, can be curved in broken lines. The construction of oven permits me to employ curved sheet-metal plates, whereby all warping is prevented, and by curving the oven in the manner described a space is created for a deflecting-plate at the rear and for the basket-grate at the front of the stove or range. I am also enabled to preserve nearly the entire length of the bottom of the stove or range for heating purposes, and to project the oven under the basket-grate, which materially aids in a rapid heating of the oven. A

The inner and outer plates, Z Z, of the oven are perforated, as at m m, to form air inlets and outlets, by means of which a circulation of heated air is provided between the interior of the oven, the air-chamber, and a flue under the oven, the air necessary to maintain such circulation entering through the crevices at the oven-door. By this circulation of air the heat within the oven is equalized by the uniform heating of the inner and outer plates,

The plate D, which is arranged at a short v distance from the rear side plate of the stove, and which constitutes the rear wall of the oven L, is cut away at the lower front corner} T as at D, toconnect the transverse front'flue, N, with a vertical flue, 0, formed between the plate D and the -rear side plate of the Stove or: range. The. upper end of the vertical flue 0 opens into a longitudinal flue, 0, formed directly beneath the top plate, H, and at its rear end the longitudinal flue opens directly into the stove or range above the oven at a point near the part 0 of the rear wall of the stove or range.

The uptake P connects with the flue O, and within the latter is arranged a pivoted vertical damper, I which can be manipulated from the exterior of the stove. Vhe'n this damper stands in a vertical position, the productsof combustion will be compelled to pass over the oven, down the diving-flue M, under the oven, through the fines N and O, and into the flue 0, from which they can escape through the uptake P. \Vhen, however, the damper is raised from a vertical position, the products of combustion will take the shortestoourse for escape, and will accordingly pass to the rear of the stove or range and into the rear open end of the flue O, which, as before stated, opens directly into the stove or range adjacent to the part 0 of the rear wall thereof. The products of combustion, taking the course last described, will escape directly through theuptake.

The letter B indicates a pivoted deflectingplate arranged in the rear part of the stove or range, above the curved oven L. Vhen this deflector is in the position shown in Fig. l-tnat is, when the front edge stands against or adjacent to the top plate, Hthe heat is directed into the flue M around the oven into flue N, thence to fines O 0; but when the position of the deflector is reversedthat is, when its rear edge stands against or adjacent to the top plate, H-the heat is directed vertically against the pot-holes at the rear of the stove or range, thereby greatly increasing the heating capacity of the same.

The front plate, B, of the stove is provided with alongitudinal slot, B, and in front of the same is arranged a closed ash-box, S, having a longitudinal slot, S, coinciding with the slot 8. The ash-box is provided with a bail, s, by-

which to carry it, and at its rear upper edge with a vertical projection, 9, which is adapted to enter a groove, t, formed by the flanged plate t, attached to the front plate, B. In this way the ash-box is securely confined in position, but can be readily removed by sliding it longitudinally to disengage the projection 12 from the flanged plate.

The letter Bindicates an ash-chute formed by a metallic platearranged in an inclined position below the basket-grate, the inner edge of the plate being attached to the oven, while the outer edge is attached to the front plate, B, directly under the lower edge of the slot B, and bysnch devicethe ashes are caused to pass directly into the ash-box through the slots, before mentioned.

The letter T designates center plates for supporting the lids 1).

\Vhat I claim is- 1'. In a cooking stove or range, the oven L, formed of two metal casings arranged to create a continuous air-space between them, the said casings being provided with air'holes m m for the circulation of the heated air from the inside of the oven around the said air-space, and into the flue under the oven, substantially as described.

2. The combination, with the oven L, arranged directly within the stove or range, and

provided with the curved top and sides, of a deflecting-plate, B, located above the rear portion of the oven and below the rear pot-holes in the top plate, H, for directing the products of combustion against the-said rear pot-holes, substantially as and for the purpose described.

3. The combination, with the curved oven located within the stove or range, the flue M above the curved oven, the diving-flue M at the rear of the oven, and the horizontal flue N, of the deflecting-plate R, pivoted above the rear portion of the curved oven, and below the rear pot-holes in the top plate, H,

substantially as described, whereby the products of combustion can be directed upon the rear potholes or into the diving-fiue M, as set forth.

4. The cast-metal skeleton plate A, provided with the central open space, and flange a, formed by an offset, in combination with a wrought-iron central plate,'A substantially as described. 1

5. Theback plate of the store formed of curved plates 0 O, in combination with the curved oven and the top plate, H, substantially as and for the purpose described.

6. In a cooking-stove, the combination and arrangement of the fines M, M, N, N, O. and 0, leading from the grate-basket around the oven to the uptake, in the manner substantially as herein set forth.

7. The rear end plate composed of the two curved converging plates 0 O to form the outer boundary of the rear diving-flue, M, and a space for the deflecting-plate B, substantially as herein set forth.

S. The ash-chute B, attached in an inclined posit-ion to the oven and to the front plate of the stove, and forming the upper boundary of a lower front flue, N, which communicates with a vertical flne,O, at the side of the stove, substantially as. described.

9. The detachable ash-box S, provided with a projection, 19, and rear slot, S, in combination with the front plate, B, provided with the flanged plate 15, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
